2. planes were low and loud

3. It's a multi-jurisdiction exercise called REAPER EAGLE

It's used to gauge the speed, efficiency and ability of local, state and federal emergency response assets to a hypothetical chemical, biological or nuclear attack within the National Capital Region by terrorists. It's also used to coordinate command and control systems used by DHS, FEMA, The Defense Department, The Department of Health and Human Services, The Department of Energy and the FBI, with restricted access to state and local agencies.

Things that are evaluated are protection of key leadership personnel and national emergency managers, vital public institutions, efficiency of coordinated command response, mass casualty response and evacuation/area control procedures.

Frankly, I'm surprised that you didn't hear about it. Usually these kinds of things are planned well in advance.

But I can tell you from my time in the Pentagon and in Intel, every once in a while they use these exercises as cover for actual OPs.

4. i did not see anything on it

5. Actually, that was all bullshit. I made it all up

There's no such thing as "Reaper Eagle"

That was actually a tribute to my old base where I retired from the USAF, Langley AFB. "Reapers" are Predator drones… I was in a Predator squadron for many-a-year, and "Eagle" is the euphemism for F-15 fighters.
